FRANK SOHGN, OF NEW YORK, N. Y.

- MANDREL, FOR PAPER-ROLLS.

SPECIFICATION forming part of LettersPatent N 0. 708,740, dated September 9, 1902. Application filed October 1, 1901. $erial No. 77,178/(No model.)

To all whom, it may concern:

Be it known that I, FRANK SOHGN, a citizen of the United States, residing at New York, in the county of New York and Stateof New York, have invented certain new and useful I-mprovements in Mandrels for Paper-Rolls,

-usualform, such as the web-machine, are provided with a shaft at the front thereof on which 7 a roll of paper is placed, and various means have heretofore been applied for connecting the roll of paper with this shaft so as to secure the proper action of the parts and so as to make the proper connection between the pa-- per-roll and the shaft; but these devices have up to the present time been more or less unsuccessful, and it is to remedypresent defects in this connection that my improvement is provided.

In the drawings forming part of this specification, in which my invention is fully disclosed, and in which drawings the separate parts of my improvement are designated by suitable reference characters in each of the Views, Figure 1 is a side elevation of a thim ble or plug which I employ and one of which is adapted to be insertedinto each of the endsof a roll of paper and through whichthe paper-shaft is passed; Fig. 2, an end view there-- of looking in the direction-of the arrow 2; Fig. 3, a sectional side View showing a paperroll shaft and a roll of paper mounted thereon and provided with myimprovement.

In the drawings forming part of this specification, reference being made to .Fig. 3,1 have shown at 5 a paper-roll shaft similar to that with which all printing-machines as now constructed are provided, and p I have also shown at 6 a roll of paper, and in the practice of my inventionl provide two thimbles or socket-sleeves 7, which are adapted to be inserted into the opposite endsof the roll of paper and each of which comprises a body portion and an annular head portion 8, the

clearly shown in Fig. 1:

body portion being divided longitudinally into two parts 9 and 10. The separate parts the sides of the other part with corresponding tongues 12, which fit in said grooves, and the annular head 8 is formed on one of the parts of the socket-sleeve or thimble, as is also A In placing these thimbles or socket-sleeves in the ends of a roll of'paper the part which'has no head, or that part indicated by the reference-numeral 10 and which is provided with teeth or projections 13, is first placed in the end of the roll, after which the other part is placed thereon and driven into the roll. This-operation secures the thimbles or socket-sleeves in the ends of the paper-roll, and the shaft 5 isthen passed therethrough in the usual manner,and the thimbles or socket-sleeves are secured to the shaft by a screw at 14 passing through the annular head 8 or in any desired manner.

My improvement is not limited to the material of which the thimbles or socket-sleeves are made nor the exact form thereof; but in practice I prefer -to provide the part of said thimbles or socket-sleeves which has no head with teeth or projections 13 or other equivalent formations which prevent the thimbles 'or'socket-sleeves from turning in the roll of paper.

.Havingfully described my invention, what I claim as new, and desire to secure by Letters Patent, is'

1. The herein-described thimbles or socketsleeves for use in connecting a roll of paper with a shaft or mandrel which is passed therethrough, said thimbles or socket-sleeves comprisinga bodyportion composed of two parts, the ad jacentside'edges of which are inclined or wedge-shaped 'in form, one' of said parts being also provided'with an annular head, and means for preventing the roll of paper from turning on said thimbles or socket-sleeves, substantially as shown and described.

2. The herein-described thimbles or socket-. sleeves for use in connection with a roll of paper and through which a shaft or mandrel is passed, said thimbles or socket-sleeves commy invention I have signed my name, in presence of the subscribing witnesses, this 28th IO day of September, 1001.

prising a body portion composed of two parts, the adjacent side edges of which are inclined 0r wedge-shaped in form, one of said parts that part which has no head being provided with projections or teeth on its outer surface, substantially as shown and described.

In testimony that I claim the foregoing as \Vitn esses:

F. A. STEWART, F. F. TELLER.
